Hey Zookie, From my personal experience when using clay marring can happen however I have also noticed if I do not use pressure on the clay and just let the lub and clay do the work there isn't marring. Mind you I was told to clay and wax and that is what I did. Would I suggest polishing after a clay? Yes. Give Vic red a try. So far I've liked it however I find that i've been going back to natty's. Something about giving natty's a cold shower after the buff that seems to prolong it's life. I could be mistaken oh well. I just put on natty's on a metallic black 350z today, tasty... Cheers, Nick
